Cyclones in Madagascar

Cyclones only occur occasionally in Madagascar. On average, they happen about 5 times a year. The hardest hit regions are Atsimo-Andrefana, Analanjirofo and Atsimo-Atsinanana.

The typical cyclone season depends on the summer monsoon. In the months before (May to June) and after (October to November), the most severe storms occur.

The most severe cyclone to make landfall in Madagascar in the past 12 months was »Emnati«. It reached a wind speed of up to 130 km/h on February 23, 2022 at 12:00 am local time near Manakara. According to the internationally accepted Saffir-Simpson classification, this corresponded to a category 1 cyclone. On the open sea, speeds of up to 213 km/h were measured (category 4).
